Abstract

En référence à la Figure 2b, la présente invention concerne un appareil transducteur (20) destiné à un aérophone à air soufflé sur arête (10), l'aérophone à air soufflé sur arête (10) ayant un trou d'embouchure (13) d'aérophone. Un haut-parleur (22) d'aérophone délivre un son à une chambre de résonance (28) de l'aérophone (10) par l'intermédiaire du trou d'embouchure (13) d'aérophone. Un microphone (23) d'aérophone reçoit par l'intermédiaire du trou d'embouchure (13) d'aérophone un son dans la chambre de résonance (28). Un boîtier (21) fournit une plaque d'embouchure (27), un trou d'embouchure (29) de boîtier étant indépendant et séparé du trou d'embouchure (13) d'aérophone. Des capteurs de respiration (24, 25, 26) détectent la respiration appliquée à travers le trou d'embouchure (29) de boîtier. Un processeur électronique (41) reçoit des signaux provenant du microphone (23) et des capteurs de respiration (24, 25, 26) et est connecté au haut-parleur (23). Les capteurs de respiration (24, 25, 26) fournissent des signaux indicatifs de l'intensité de respiration. Le processeur électronique (41) génère un signal d'excitation qui est délivré sous la forme d'un signal d'excitation acoustique à la chambre de résonance (28) par le haut-parleur d'aérophone. Le processeur électronique (41) utilise les signaux qu'il reçoit pour déterminer une note musicale souhaitée qu'un joueur de l'aérophone souhaite jouer. Le processeur électronique (41) synthétise la note musicale souhaitée et délivre la note synthétisée à un ou plusieurs éléments parmi des écouteurs (43), un haut-parleur (44) externe à l'appareil transducteur (20), un appareil informatique (45) et/ou un téléphone intelligent, la note musicale étant par là-même jouée de manière audible et/ou affichée visuellement à l'attention du joueur.
